from ever since和since then和after that time和from then on的区别？

Question

如题所述

Answer 1

没有from ever since，只有ever since
ever since，since在这里作副词，两个意思
1.ever since=since then 自从那时起，用现在完成时
2.ever since=since，起连词作用
It is 10 years ever since (since) we graduated from school
since then,这里since作介词，用现在完成时，从那时起
after that time,从那以后，用现在时或将来时
from then on,自那时起，用过去时
From then on, try as I may, I began to become very cool toward her
